Merge Coplanar

Is there a way to merge coplanar surfaces inside transmutr (akin to function of the ThomThom cleanup tool)

I find that when I export FBXs from Rhino it will make crazy faceted surfaces for what are otherwise coplanar. Of course I can do that after import with the Cleanup tool however it would save some time as the export process from transmutr and opening time takes a while.

The one workflow I thought could work is to mesh the surfaces in Rhino, and then merge them in Rhino before the export. However I found that merging the surfaces, while they look good in Rhino, things like window openings on surfaces get filled in on import

No, this is currently not possible in Transmutr.
